BOTTLE OR JAR CLOSURE.

To all whmn it may concern:

Be it known that I, CHRISTOPHER DovE- ing from the inner wall ofthe neck portion,

each of said lugs taperin toward one end to the extremity thereof an forming a rounded shoulder, and a stopple having a body portion adapted .to be inserted in the neck of said bottle and a rim encircling said body portion at the top thereof and preferably forming art therewith androunded flanges forming eads ru in an oblique direction from the lower en thereof and tapering toward each end and disappearing into said body portion and adapted to be turned to pass over the aforesaid curved shoulders and on their upper sides engage the lower sides of the aforesaid lugs. y

The objects of the invention are to eliminate all metal parts in bottle or jar closures, to provide a reliable air-ti ht closure readily opened or closed at the wi l of the user, and in this particular type of bottle to obviate the dangers incident to the chipping and grind- I of glass usual to such constructions where customary in the formation of glass parts meet.

In the drawings, Figure 1 is a pers ective view of the body portion and neck of t e bottle. Fig. 2 is a perspective view of the stopple to be inserted into a bottle, such as illustrated in Fig. 1. 3 is a sectional elevation of a bottle having the stopple secured therein. Fig. 4 is a s de elevation of the stopple illustrated in Fig. 2. 5 is a side ele: vation of a slightly-modified form of stopple.

Like letters of reference indicate corresponding parts in each ure.

In the drawings, a is t e body portion of the bottle, from which extends upwardly, as

ottles, the neck I). l fl 1 0 re resents s or an es, ro'ect' aterall irom the i fl ner wall f thb nelck h f the bott e in proximity to the upper edge thereof Specification of Letters Patent.

and arranged diametrically opposite one to the other. Each of the lugs or flanges c is rounded to form a bead from the interior wall of the bottle-neck, and toward one end thereof the under side inclines gradually at d to the upper side and disappears in the wall of the bottle, forming the rounded shoulder e.

f is a stopple having the body portion g and the rim h encircling said body portion at its upper end and forming part therewith. The said body portion 9 is dimensioned to be inserted into the neck 1) between said lugs c.

i represents flanges in the form of rounded I beads projecting from the periphery of and forming part with the body portion 9 at the lower en lique direction, each of said beads partly encircling said body portion and gradually shallowing and disappearing therein at each end in order to leave free and clear spaces between said flanges -to pass the lugs c on the insertion of the stopple n the bottle. a

j is an annular groove or recess formed in the enlar ed upper portion 1c ofthe body ortion g and the rim h and having a curved ed.

l is a gasket introduced into the groove j, and when the stopple is in position contacting with the upper eveled edge m at the top of the bottle-neck. In applying this stopple to the bottle the gasket is put in place on the of its sides and running in an 'obstopple in the groove j, and when the bottle has een filled with the matter or substance tobe contained therein the body portion 9 of the stopple is inserted in the neck I) of the bottle.

In order to avoid the obstructions in the form of the lugs or flanges c, the body portion of the stopple is inserted so that the sides of said body portion, clear of flanges, pass over said lugs or flanges c, and just so soon as the body portion is in to its full extent it may be then turned, which brings the upper sides of the flanges i in contact with. the lower sides of the lugs or flanges c, and the more the stopple is turned the tighter in place it will be, as the upward inclination of the top sides of the flanges i in contact with the lower sides of the lugs or flanges c wedge the stopple firmly, and bringing pressure to bear on the gasket Z the latter is squeezed in between the bed of the groove j and the beveled edge m.

In Fig. 5 a-slight modification is shown in the projecting flange from the body portion, and in this ure it will be seen that the inclination of t e upper side of the flan e is from each end running toward the mid e of surface of the bead of the stopple.

said flangethat is to say, the flange tapers from the middle to the end, thus providing a flange in which the stopple on being inserted may be turned either way and yet tighten up 1n the similar manner, as herein described.

In this invention the salient features are the forming of the beads both on the stopple and on the neck of the bottle in order that the grinding and chipping effects in such construction will be entirely done away with. It is most essential to have the beads on the bodyportion of the stopple formed so, particularly at their ends, but also throughout their length, as to meet the corresponding surfaces of the lugs without the passage being obstructed by any rough or sharp 'corners, and thus prevent the chipping or grinding of glass and the deposit of said pieces of glass into the bottle. In the present construction the pressure on the gasket against the beveled surface on the neck may be brought to bear without fear of this. grinding and chipping effect, as thebead from the neck at the lowermost point on its upper side meets the inclined surface of the lug and passes easily over the curved shoulder to the under side of the lug, which is also rounded to correspond with the rounded Thus the fastening is securedwith ease, insuring a reliable and air-tight joint.

What I claim as my invention is 1. A bottle or ar closure, comprising abottle having lugs or flanges projecting from the inner wall of the neck and forming rounded beads disappearing into said interior wall at each end thereof, and a stopple having a body portion to be inserted in the neck of said bottle and a rim encircling said body portion at the top thereof and forming part therewith and flanges forming rounded beads on the pe- 4o riphery of said body portion toward the lower end and running in an oblique direction and adapted to engage on their up er side the lower side of the aforesaid beads om the bottle-neck, as and for the purpose specified.

2. A bottle or jar closure, comprising a bottle having lugs or flanges forming rounded beads from the interior wall of the neck portion, said beads havin their under sides incline upwardly towar one end thereof and form a rounded shoulder on said under side, the said lu gradually taperin from said shoulder and disappearing in sai wall, and a stopple having a body portion to be inserted in the neck of said bottle and a rim forming part therewith encircling said body portion at the top thereof and an annular groove or recess between said rim and body portion in an enlarged part of the latter, said recess having a curved bed and flanges projecting from the periphery of the body portion toward the lower end thereof forming rounded beads extending in an oblique direction thereon and at each end thereof disappearing into the said body portion, and a corresponding gasket inserted in said roove or recess, as and for the purpose speci ed.
